the hydrous phases in a rock, meaning that the amount of melt generated through these reactions is controlled by the abundance and stability of specific hydrous phases. Depending on the tectonic setting, water can also be introduced to the system through the dehydration of a subducting hydrated oceanic plate or magmatic underplating.

Rock type

The composition of a parent rock has a direct effect on the composition of the resulting melt. Granitic melts are commonly classified based on the
